Most items can be freely returned or exchanged, regardless of whether it is a quality issue or a problem related to personal preference. However, some special goods are not subject to return or exchange, such as personalized items, pet merchandise, etc. Before sending the personalized products, we will confirm the visual display of the products with the customer, and then send the goods. Since these are personalized products, we do not support returns or exchanges. If the pet goods have already been opened and tried, we cannot offer a return or exchange service, as we need to prevent infection from the disease in the pets. If you have more questions, you can contact us, and we will give you more answers. Thank you.
